This invention. relates to improvements in enjc'ejto an improved form ofBunsen burner adapted tov be readily'connected to or disconnected from agas supply pipe or the like.

In many gas burner installations; as for example, in gas broilers; waterheaters, etc, it. is frequently necessary to remove the burners forcleaning, adjustments or repairs. The devices in use prior to thisinvention have been objectionable because" such burners haveriotbee'ncapable of convenient removaland replacement; Usually they have0 i11 eluded vthreaded have required manipulation, and in many instancesthe burners have requi-redtilting into difierent planes during'jinsertion or removal; These and other objections are overcome by thepresent inventiom which in its broader aspects contemplates a gas'burnerconnection of such a character fth'atgthe burner may be removed fronrorapplied to a gas nozzle bya directlater'al movement relaf tive to saidnozzle. f V V lMore specifically, the invention 'c'ofrnpre; hends theprovision of a gas burnerfof the Bunsen type havingja gas tube and a gasnozzle. so constructed andarranged as to per- Init relative movement ina directiont an verse to the. axis ofthe gas nozzle. c I 1 Anotherfeature of. he invention is" the provision. of. such a device withimproved and, simplified. means for holding the burner and: nozzleagainst accidental displacement such means being preferably in orporated'with a shutter valve.

Another feature. of the invention resides the provision of an improvedshutter valve for controlling admission of primary'airjto theburner. f

Other features and. advantages .wjflf be apparent from the followingdescription,

reierence being had to the. ccompa ying drawings, wherein'ioneembodiment of the invention is shown. by way oi illustration,

' In the shown as apgned to a gas broiler; but if is not restric te vtofsuch use it is equally adaptable-for use in' 'other' environments:Such an installation my comprise a broil-ing oven 10 of any ordinary orpreferred design,

and equipped with Bunsen ,burners ,11, here shown astwo in nixmber, (mat each side of;

the o'venq' The two burnersll arealike'; and therefore'a detaileddescription" of one will sufiice to; conveyafull understandingfofi'theinvention. c' a Each burner 11' comprises a horizontal member or burnerproper l25 proviided with a plurality of'su'itable flameports 13, we

erably di're'ctfed toward the interior 0; the

broiler. The member '12 is hollow. "and 'e'xtendsthrough the front; wallof the oven 10, beingxremovably mounted, and having its inner endsupgortedin such position'by I,

meansof a lug 1 see'. Figure; 2; in engage meat with a suitablesupport'notishown. mixingi'tube" 15 communicates with thememe ber"12 andmay preferably beffior'med integral therewith extending' downwardlyoutside of the oven and toward a gas supply pipeorm nimdie The mixing.tube 15 is preferably tapered as sh'qwn', and adjacent its extremity,the walls of said tube flare outwardly to form an enlarg ed mouth 17havingl'a transverse web 18- at its outer end. f Ex ndi g. u rd ro gh ali el orifice 19. in the web 1.8i'i'sj a gas nozzle 26 Whlfil'iterminates; within L the mouth 1? and if ffit fleb d to the gas. upp y?wa he K I p v drawings, the invention has been mary air to themixingtube, the web 18 is provided with a plurality of openings 22, hereshown as two in number, of general sector shape, and disposed atopposite sides of the orifice 19. The mouth of the mixing tube isfurther provided with a shutter valve. 23 for controlling the amount ofair passing through the openings 22, said valve being preferablycup-shaped and rotatably mounted in close engagement with the web 18 andouter wall of the mouth 17. The web 24 of the valve 23 is similar to theweb 18, being provided with a central orifice 25 through which thenozzle 20 is adaptedto extend and with a pair of apertures 26 forselective registration with the openings 22.

It will be evident that, with a construction as thus far described,"theburner could only be removed from operativeposition in the broiler bylifting the burner with its shutter valve until it has cleared the endof the 'nozzle20 and then moving itlaterally, and the same operationsare necessary, in reverse order, to replace the burner. limitation hasconstituted a serious clefectin therart, which the present inventionovercomes. j v

To'this end, the web 18 is formed with. a slot 27 which extends radiallyfrom the central orifice 19 in the same direction as the burner member12,. and continues into the wall of the mouth portion 17 to a pointabove the end of the nozzle 20. Similarly, the shutter valve 23 isformed with a slot'28 extending radially from the orifice 25 and throughits side wall 29. In order to reinforce the web 24 of the valve, themarginal edges of the slot 28 and orifice25. may be thickened as at 80,which is additionally advantageous in that it provides a greater surfacefor the web against the side of the nozzle. It will be seen that withthe mixing tube 13 and shut ter valve 22 constructed as thus described,the gas burner 11 can be set in place, as shown in Figures 1' and 2,with a direct lateral movement, or a movement in a direction transverseto the axis of the nozzle, and

without. changing the plane of the burner.

When first assembling the parts, the valve is positioned on the end ofthe mixing tube with the slots 27 and 28 in registration, whereupon thehorizontalmember- 12 isinserted in the wall of the oven 10 and pushedrearwardly until the nozzle arrests further movement by contact with theedge of the, orifices 19 and 25 as shown in Figure 6.

This

The valve may then be rotated to a position such as shown in Figure 5 orany intermediate position dependent upon the amount of air desired inthe mixing tube. It is to be noted that when't-he valve is thus turned,it positively prevents accidental displacement of the burner relative tothe nozzle by virtue of the nozzle being engaged at opposite sides bythe edges of the respective orifices 19 and When it is desired to removea burner from the broiler, the valve 23 need only be rotated until itsslot 28 overlies the slot 27 inthe end of the mixing tube, whereupon theburner and its associated parts may be withdrawn by a direct lateralmovement, as indicated dotted linesin Figure2.

From the foregoing it will be obvious v a substantial improvementhasbeen made in the gas burner art. In ltSbIYQLdBI aspects,

maybe applied to a wide variety of gasheaters without departing from thescope of the nventlon or sacr ficing its ch ef advantages.

Havingthus de'scribed my invention, what I claim is 1. In a Bunsenburner,a'mixing tube, a

gas nozzle extending into the endfof said tube, one side of said tubebeing slotted at its extremity to provide clearance for said nozzle, andlocking means attached to the mixing;tube,1 said locking means beingformed. so as to selectively obstruct or'uncover the slot in the mixingtube. 2. In a Bunsen burner, a mil ing tube having an openmouth, thewall of the tube being slotted at one side of said mouth to permitlateralpassage of a gas nozzle which extends intosaid'mouth, andashutter valve rotatable on the mouth andabout the gas nozzle, saidshutter valve having a slot adapted for registration with the slot inthe tube wall, such construction preventing relative" lateral :movementbetween the nozzle and the tube when said slots are out of registration.

y 3. A Bunsen burnerprovided with a mix ing tube having a web at itsmouth formed with an air inlet, a shutter valve rotatably mounted uponsaid mouth and being formed withan aperture adapted toregister with saidair inletJsaid tube and shutter valve being formed each witha slotadapted'to be brought into or out of registration with each other;whereby the burner may be applied to or removed from a gas nozzle by arelatively lateral movement, and whereby the shutter valve may berotated to regulate the supply of air to the tubeand also to lock thetube in place.

bination, a gas burner having a mixing tube formed with a Web at itsmouth, said Web being apertured to provide an air inlet, a gas nozzleextending into the end of said mixing tube, and a shutter valverotatable about the nozzle and on the end of said tube,

the web of the tube and the shutter valve of the part.

In testimony whereof, I
